rated load, and is expressed in a ratio based on the rated load current for 1 minute. The overload
capacity on the ”S” Series inverter is 150%/1min for heavy loads, and 120%/1min for normal
loads.

The current rating differs from the load rating, as it also has an ambient temperature limit. For
derating specifications, refer to 11.7
Continuous Rated Current D.

2nd Motor Operation
The 2
nd
motor operation is used when a single inverter switches between two different motors.
When using the 2
nd
motor operation, set the parameters for the 2
nd
motor in the M2 group. The 2
nd
motor parameters are used when a digital input terminal, defined as a 2
nd
motor function is
activated.

nd
motor group) group. An input signal to the digital input terminal will operate
the motor according to the M2 parameter settings listed below. The inverter
cannot be switched to the second motor while running.
Pr.50 (Stall Prevent) must be set first to view M2.28 (M2-Stall Lev) settings. Also,
Pr.40 (ETH Trip Sel) must be set first to view M2.29 (M2-ETH 1min) and M2.30
